LASTING APPARATUS.

Specification of Letters Patent.

Patented Feb. 29, 19116.

To all whom it may concern Be it known that I, ALBERT A. MACLEOD, a citizen of the United States, residing at Swampscott, in the county of Essex and State of Massachusetts, have invented cer tain Improvements in Lasting Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, likereference characters on the drawings indicating like parts in the several figures.

This invention relates to lasting devices and is herein shown and described, by way of exemplification merely, as embodied in lasting pincers for use in lastiru shoes upon machines which are provided with wipers or wiping devices which are adapted to treat at one operation a substantial portion of the margin of the upper, as, for example, in lasting the toe or heel of a shoe upon bed lasting machines.

It frequently happens in the operation of wiping up the toe portion of the shoe by the wipers of the lasting machine thatuneven distribution of the stock causes folds or wrinkles to be formed in the upper material. These Wrinkles the operator attempts to remove by pulling the partially lasted material upon each side of the fold or wrinkle by means of hand lasting pincers. In effecting this he seizes the upper upon one side of the fold and pulls it upwardly and somewhat laterally and then seizes it upon the other side of the fold and pulls it upwardly and laterally in the opposite direction. In either case, however, the leather on the side of the fold opposite to the part pulled is not held against the action of the pincers and it is difficult entirely to remove the plaits or wrinkles without repetitions of this time consuming operation.

The object of this invention is to provide means for enabling the operator to remove a wrinkle from the upper more expeditiously.

As an important feature of the invention, means is provided which may take the form of hand lasting pincers for seizing the upper on each side of the wrinkle at the same time and stretching the gripped portion of the upper transversely of the wrinkle, and thereby redistributing the fullness to eliminate the wrinkle.

As a further feature of the invention the stretching of the upper transversely of the wrinkle is effected at the same time that tenslon s applied to the upper to draw it farther into lasted position, and furthermore it 1s characteristic of the preferred embodiment of the invention that the pulling ten- $1011 on the upper and the transverse wrinkle-removing strain are directly proportional to each other.

The invention as herein shown and described is embodied in a hand pincers of the general type of construction which lasting machine operators are accustomed to using, such pincers having curved gripping jaws and an abutment formed as a hammer head which may be used as a fulcrum about which to rock the jaws for tensioning the upper. For embodying the present invention, the jaws of the pincers are each formed in two lateral sections, each of which is pivoted about an axis extending perpendicularly to the gripping faces of the jaws to the jaw carrying portion of the pincers, that is, the pincer jaws are each divided into two sections in a plane perpendicular to the gripping faces of the jaws and the said sections are laterally movable relatively in a direction transverse to that plane. The jaws are normally held open to seize the upper but with the lateral sections close together. Means is provided comprising a lever pivoted between its ends for effecting the separation of the lateral sections of the jaws for spreading the gripped portion of upper transversely of the tensioning strain to remove wrinkles therefrom.

These and other features of the invention may be understood more fully from the following description and the appended claims when taken in connection with the accompanying drawings, in which,

Figure l is a perspective view of a pincers provided with an embodiment of the present invention, the pincers being in position to act to seize and spread laterally the portion of the upper to be pulled; Fig. 2 is a similar view showing the position of the parts after the completion of the separating movement of the jaw sections.

The usual pincer handles 2, 4 are provided which are crossed and pivoted for limited movement upon a rivet 6 as usual. The handle members are formed in front of the pivot with ears 8. To the ear of the handle member 4 is connected by a vertical pivot one or both of the sections 12, let of the upper jaw and the sections 16, 18 of the lower jaw are similarly connected to the ear on the handle member 2. Each jaw member is here shown as having a notch 20 on its inner side and these notches together form, when the jaws are closed, an opening through the jaws which extends in a direction substantially perpendicular to the gripping faces of the jaws. The sides of the opening are preferably inclined with their approaching edges toward the outer ends of the jaws for a purpose that will presently appear. The handle member 2 carries on its under side a hammer member 22 through an opening in which from front to back passes a double curved lever 24 pivoted at 26 in the member 22. The front end of the lever 24 is upwardly directed and passes through the opening between the lateral sections of the jaw members. This end is preferably wedge-shaped in cross-section to correspond more or less closely to the shape of the opening in which it is located. The opposite end of the lever is directed downwardly to bear upon the insole of the shoe being lasted.

It will be obvious that when the stock is seized by the jaws, in the position of Fig. 1, and pressure is brought to bear on the downturned end of the lever, the opposite end of the lever will be forced through and toward the endsof the jaws and will cause them to separate and hence effect a spreading laterally of the gripped portion of up per. When the pressure on the lever 24: is released the springs 30, of which there is one on each side of the pincers, if both jaw sections are pivoted, cause the lateral halves of the jaws to return to their normal positions, while the spring 32 separates the gripping faces of the jaws, as will be readily understood.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is l. A device for use in lasting shoes comprising jaws for seizing the upper upon each side of and closely adjacent to a. wrinkled portion of upper, and means for moving the jaws apart transversely of the wrinkled portion to remove the wrinkle, said transverse movement taking place automatically as an incident to the operation of the device in tensioning the stock.

2. A device for use in lasting shoes, comprising jaws for seizing the upper upon each side of a wrinkled portion of upper, and means arranged to contact with the work and to be pressed against it as the upper is tensioned, said means acting to separate the jaws with a force proportional to the upper tensioning force.

3. A hand lasting tool having crossed hand levers carrying pincer jaws, the jaws 4. A hand tool for lasting comprising jaws, means whereby they may be operated to grip the stock, said jaws being formed in separate parts movable laterally, and means rendered effective by movement of the said operating means to produce separation of the jaws while the stock is gripped by the aws.

5. A lasting device comprising two pairs of cooperating jaw sections, means whereby the jaws may be operated to grip the stock and means by which the jaw sections may be separated substantially in the plane of the gripped portion of stock to spread the stock laterally. i

6. A lasting device comprising two pairs of cooperating jaw sections, means whereby the jaws may be operated to grip the stock and tension the same, and means operated during the tensioning of the upper to spread the stock laterally by. separation-of the jaw sections laterally.

7. Lasting pincers comprising crossed handle levers, jaws pivoted to said levers and operating in pairs to seize the work, and a lever arranged with one end between said pairs of jaws, said levers being formed to separate the jaws when moved relatively thereto and arranged to be moved automatically when the pincers are used .to tension the upper. V i

' 8. Lasting pincers having two pairs of gripping jaws adapted for engaging adjacent portions of an upper, which pairs are mounted for relative movement in the plane of their gripping faces, and means for so moving the pairs of jaws apart as an incident to the pulling of the stock.

9. In a lasting tool, two pairs of gripping jaws mounted upon the same operating means for relative lateral movement substantially in the plane of the upper to tension the gripped stock laterally, and means for effecting said relative movement later ally as an incident to the normal use of the tool.

10. In a lasting tool, operating handles, two pairs of jaws having a fulcrum and pivoted for relative movement on the handles in addition to their opening and closing movement, and means actuated'by pressure of the tool upon its fulcrum for laterally moving the pairs of jaws relatively.

11. A lasting pincer comprising jaws having operating handles and a fulcrum, and additional means by which the jaws will be given, when tension is applied to the upper, operative movements substantially in the plane of their gripping faces.

12. A lasting pincer comprising jaws having operating handles and a fulcrum, and additional means which is rendered active as a result of the fulcruming movement to actuate the jaws to tension the stock in a direction at an angle to the tensioning effectcd by the fulcruming movement.

'13. A lasting pincer comprising jaws having operating handles and a fulcrum block, and a lever pivoted in the fulcrum block and extending rearwardly therefrom to engage the sole and forwardly therefrom to move the jaws when the lever and fulcrum block are relatively turned.

14-. A lasting pincer comprising jaws having operating handles and a fulcrum, each jaw being divided lengthwise into a plurality of sections which are relatively movable laterally, and means for maintaining the sections of each jaw in normal relation to each other.

15. A lasting pincer comprising jaws and operating means by which the jaws may be caused to seize and pull an upper, each jaw being divided lengthwise into a plurality of sections which are relatively movable to tension laterally the portion of upper held between the sections.

16. A lasting apparatus having, in combination, pincer awe and operating means by which the jaws may be caused to seize and pull an upper over a last bottom, said jaws being divided longitudinally in two sections, and means operated by the pulling movement of the pincers for automatically separating said sections laterally to distribute fullness in the gripped upper.

17. A tool for use in lasting shoes com prising two pairs of jaws constructed for seizing an upper and arranged one upon each side of a wrinkle and adjacent thereto, means for effecting a movement of the jaws to tension the upper over the last, and means for automatically manipulating the jaws relatively to remove the wrinkle during the tensioning operation.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
